Spacing between two successive nodes in a standing wave on a string is $x$ . If frequency of the standing wave is kept unchanged but tension in the string is doubled, then new spacing between successive nodes will become
Each of the properties of sound listed in column $A$ primarily depends on one of the quantities in column $B$. Choose the matching pairs from two columns
The figure shows four progressive waves $A, B, C$ and $D $ with their phases expressed with respect to the wave $A$. It can be concluded from the figure that
A sonometer wire, with a suspended mass of $M = 1\, kg$, is in resonance with a given tuning fork. The apparatus is taken to the moon where the acceleration due to gravity is $(1/6)$ that on earth. To obtain resonance on the moon, the value of $M$ should be ......... $kg$
A source and an observer move away from each other with a velocity of $10\; m/s$ with respect to ground. If the observer finds the frequency of sound coming from the source as $1950 \;Hz$, then actual frequency of the source is .... $Hz$ (velocity of sound in air = $340\; m/s$)
Equation of the progressive wave is given by : $y = a\sin \pi (40t - x)$ where $a$ and $x$ are in metre and $t$ in second. The velocity of the wave is ..... $m/s$
A speaker emits a sound wave of frequency $f_0$. When it moves towards a stationary observer with speed $u$, the observer measures a frequency $f_1$. If the speaker is stationary and the observer moves towards it with speed $u$, the measured frequency is $f_2$. Then,
